Please, as a kindness to me! Give examples for WPF 2010 as code of Visual C# does not work in WPF 2010.
请，作为对我的善意！给出 WPF 2010 的示例，因为 Visual C# 的代码在 WPF 2010 中不起作用。

If you want to set focus on last added rowthen try this code:
如果要设置，请focus on last added row尝试以下代码：
dataGridView.ClearSelection();
int RwIndex= dataGridView.Rows.Count - 1;
dataGridView.Rows[RwIndex].Selected = true;
dataGridView.Rows[RwIndex].Cells[0].Selected = true;

For WPF you have to add gridview control inside Listview, after that you can easily select and focus particular record in Gridview.
Otherwise you must have to use DataGrid Control for this kind of stuff.
对于 WPF，您必须在里面添加 gridview 控件Listview，之后您可以轻松地在 Gridview 中选择和聚焦特定记录。否则，您必须使用 DataGrid Control 来处理此类事情。
For example (Listview)refer this code:
例如(Listview)参考这个代码：
myListView.SelectedItem = myListView.Items[index];
myListView.ScrollIntoView(myListView.Items[index]);
ListViewItem listViewItem = myListView.ItemContainerGenerator.ContainerFromIndex(index) as ListViewItem;
listViewItem.Focus();
For example (DataGrid):
例如(DataGrid)：
int index = 11;
myDataGrid.SelectedItem = myDataGrid.Items[index];
myDataGrid.ScrollIntoView(myDataGrid.Items[index]);
DataGridRow dgrow =(DataGridRow)myDataGrid.ItemContainerGenerator.ContainerFromItem(myDataGrid.Items[index]);
dgrow.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
